Simulation of Coolant Flow and Heat Transfer for Hydraulic Free Piston Engine Water Jacket

摘要

The development of hydraulic free piston engine (HFPE) in China is still in the beginning stage of exploration. Based on the project of research group, the coolant flow and heat transfer of water jacket's for the HFPE were simulated with the three-dimensional CFD software FLUENT, and the field information of the velocity field, pressure field and the transfer coefficient of coolant in the water jacket were achieved. The results indicate that the requirement of cooling system can be meet except some small problems, but it provides a reference for the engine design in the future.
